If you’ve used Ubuntu a while, you might remember GNOME applets – icons that sat on your panel and gave you access to controls and information. If you miss panel applets, try installing third-party indicator applets for Ubuntu’s Unity desktop.
There are a wide variety of indicator applets available for Unity, most of which aren’t available in Ubuntu’s default software repositories. The commands to install the indicator applets provided here were tested on Ubuntu 12.04.
After installing an indicator, you may have to search for it and activate it from your Dash, launch it with a command, or log out and log back in. This behavior depends on the indicator.
The weather indicator applet provides constantly updating weather information right on your panel. Install it with the following command:
Launch the Weather indicator from the Dash after installing it.
sudo apt-get install indicator-weather
2: System Load / Performance
The system load indicator shows you graphs of your system performance on your panel – like the old GNOME System Monitor applet used to. It shows a graph of your CPU activity by default, but it can show graphs for more than one type of resource at a time – from its preferences, you can enable graphs for network activity, memory, and other system resources.
Launch this indicator from the Dash after installation.
sudo apt-get install indicator-multiload
3: CPU Frequency
The CPU frequency scaling indicator shows you the current speed of your CPU and lets you control its policy – for example, you can force a certain CPU speed, enable power-saving mode, or enable high-performance mode.
Launch the indicator by running the following command after installing it:
sudo apt-get install indicator-cpufreq
4: Ubuntu One
If you use Ubuntu One, you might want an indicator applet that shows you Ubuntu One’s status – including your current file transfers and available space – without having to open Ubuntu One’s configuration window. The unofficial Ubuntu One indicator provides this information. Install it with the following commands:
Log out and log back in. The indicator will automatically start.
sudo add-apt-repository ppa:rye/ubuntuone-extras sudo apt-get update sudo apt-get install indicator-ubuntuone
5: Classic Menu
The classic menu indicator provides a classic, GNOME 2-style menu on your panel in Unity. Install it with the following commands:
Launch ClassicMenu Indicator from the Dash after installing it.
sudo apt-add-repository ppa:diesch/testing sudo apt-get update sudo apt-get install classicmenu-indicator
6: Recent Notifications
The recent notifications indicator provides a list of recent notifications that Ubuntu has shown to you – anything that came through the notification daemon appears here. You’ll be able to view all your recent notifications, even if you were away from your computer when they appeared.
Log out and log back in. The indicator will automatically appear.
sudo add-apt-repository ppa:jconti/recent-notifications sudo apt-get update sudo apt-get install indicator-notifications
The touchpad indicator allows you to easily disable and enable your laptop’s touchpad — right from the panel. Run the following commands to install it:
After installing the indicator, launch it from your Dash.
sudo add-apt-repository ppa:atareao/atareao sudo apt-get update sudo apt-get install touchpad-indicator
8: Hardware Sensors
The hardware sensors indicator shows you information from your system’s hardware sensors, such as the temperatures of your system’s hardware and the speed of its fans. Install it with the following commands:
Launch the indicator from the Dash after installing it.
sudo add-apt-repository ppa:alexmurray/indicator-sensors sudo apt-get update sudo apt-get install indicator-sensors
The caffeine indicator allows you to prevent Ubuntu from going to sleep. For example, this may be useful if you’re watching videos in an application that doesn’t automatically inhibit Ubuntu’s sleep behavior. Use the following commands to install it:
Launch Caffeine from the Dash after installing it.
sudo add-apt-repository ppa:caffeine-developers/ppa sudo apt-get update sudo apt-get install caffeine
The keylock indicator applet shows you whether your caps lock, num lock, or scroll lock keys are on. Use these commands to install it:
Launch Indicator-Lockkeys from the dash after installing it.
sudo add-apt-repository ppa:tsbarnes/indicator-keylock sudo apt-get update sudo apt-get install indicator-keylock
